While the photovoltaic power generation industry is rapidly developing, land resources are increasingly limiting traditional land-based photovoltaic power plants. Consequently, floating photovoltaic power generation has emerged as a new form of photovoltaic power generation.

[0003] Floating photovoltaic power generation refers to the construction of floating photovoltaic systems in water environments such as ponds, reservoirs, lakes and sea surfaces. It can effectively and comprehensively utilize water bodies and solve the shortcomings of traditional photovoltaic power generation that it occupies a large area.

However, in areas with rough seas or other waters with large wave fluctuations, the floats are subject to large impact forces, and the connections between the floats are easily disconnected due to the impact, causing the floating photovoltaic system to disintegrate.

[0005] Therefore, existing floating photovoltaic systems have high design requirements for connectors and connection structures, and high maintenance costs. These have restricted the development of floating photovoltaic systems and require further optimization. Utility Model Content

[0035] In addition, the terms "first", "second", etc. are only used to distinguish in description and have no special meaning.

[0036] See also Figure 1 and Figure 2 As shown, this embodiment provides an offshore photovoltaic floating body, including a floating body unit 1, wherein the floating body unit 1 is respectively provided with a connecting portion at both ends in a first direction, and the connecting portion includes two clasping ears 11 protruding from the end surface of the floating body unit 1 along the first direction, the two clasping ears 11 are arranged opposite to each other, and a connecting gap 12 is formed between the opposite surfaces of the two clasping ears 11, and the connecting gap 12 is used for installing a connecting member 2 fixed to another floating body unit 1, and reinforcing ribs 13 are respectively provided on the opposite sides of the two clasping ears 11 and the end surface of the floating body unit 1.

[0037] Therefore, the unique shape of the connecting part allows the spaced double ears 11 structure to be simply plugged into the connecting part, and then cooperates with the fasteners 3 to achieve a reliable connection, so that the two connected floating unit components 1 have no height difference, the force is more evenly distributed when subjected to impact, and the connection is not easily damaged, which greatly improves the structural stability of the floating photovoltaic system and reduces maintenance costs.

[0038] Optionally, the two tangs 11 are arranged along a second direction, which is perpendicular to the first direction; a plurality of reinforcing ribs 13 are arranged along a third direction, which is perpendicular to both the first and second directions. Specifically, the first direction is the length direction of the floating unit element 1, which is parallel to the horizontal plane; the second direction is the height direction of the floating unit element 1, which is perpendicular to the horizontal plane; and the third direction is the width direction of the floating unit element 1.

[0039] Furthermore, the reinforcing ribs 13 on the opposite sides of the two holding ears 11 are aligned one by one in the second direction, ensuring that the two holding ears 11 are subjected to the same force, and the force is evenly and effectively dispersed when connected to the connecting member 2.

[0040] Optionally, a first fixing hole 14 is provided on each lug 11 and between two adjacent reinforcing ribs 13. The first fixing hole 14 is used to install a fastener 3 passing through the connector 2. The distribution positions of the reinforcing ribs 13 and the fastener 3 are reasonably designed to ensure reliable fixation while avoiding stress concentration.

[0041] Optionally, a mounting groove 15 for installing a photovoltaic bracket is provided on the floating unit 1, and a second fixing hole 16 is provided at the bottom of the mounting groove 15. The second fixing hole 16 is used to install a fixing part fixed to the photovoltaic bracket to ensure that the floating unit 1 is reliably connected to the photovoltaic bracket, and the sinking installation can avoid displacement of the photovoltaic bracket.

[0042] Optionally, third fixing holes 17 for anchoring are respectively provided on both sides of the floating unit 1 in the first direction, so as to facilitate binding the floating unit 1 to the bottom of the water or other fixed objects, ensuring that the position of the floating unit 1 is basically stable and meeting the requirements of building photovoltaic brackets over a large area.

[0043] On this basis, see Figure 3 and Figure 4 As shown, this embodiment also provides a connection structure of an offshore photovoltaic floating body, including a connection member 2 and the above-mentioned offshore photovoltaic floating body, the offshore photovoltaic floating body including a floating body unit 1, the floating body unit 1 is provided with a connection portion, and the connection portion is provided with a connection gap 12;

[0044] A connector 2 is installed between the two floating unit components 1. One end of the connector 2 is inserted into the connection gap 12 of one floating unit component 1 and locked, and the other end of the connector 2 is inserted into the connection gap 12 of the other floating unit component 1 and locked.

[0045] Thus, the floating unit elements 1 with uniquely shaped connecting parts are connected in sequence through the connecting parts 2, and the connecting parts 2 are inserted into the connecting gaps 12 of the connecting parts and locked, thereby ensuring a reliable connection and convenient installation, with low requirements for the connecting parts 2, and improving the impact resistance of the floating photovoltaic system.

[0046] It should also be noted that the floats of existing floating photovoltaic systems are directly connected by connecting parts. Once the connecting parts are damaged under the action of impact force, the entire float can only be replaced, which is very costly. The floating unit 1 strengthens the structure of the connecting part and is connected with a connecting part 2. Compared with the connecting part, the connecting part 2 is more easily damaged. If the connecting part 2 is damaged, it can be replaced separately, which greatly reduces the maintenance cost.

[0047] Optionally, a fastener 3 passing through the connection gap 12 and the connector 2 is installed on the connection part of the floating unit 1. The fastener 3 is preferably a bolt and nut, which has the ability to lock the connector 2 and tighten the two ears 11. Other fastening methods may also be applicable. The specific form of the fastener 3 is not further limited here.

[0048] Optionally, the connector 2 is in the form of a flat plate, and a through hole is formed on the connector 2 for the fastener 3 to pass through. Based on the above-mentioned double-hugging ears 11 structure, the connector 2 does not need a complex design, and only needs to be cut and perforated by the plate, which greatly reduces the design requirements of the connector 2, reduces the cost of parts, and is also easy to replace.

[0049] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
